The components 1 and 2 or 10 and 2 ¹ can be viewed as movable with respect to the other components of the inhaler, as can be seen from a comparison of FIGS. 1 and 4.

The inhaler further comprises stop sleeves 7i 7 '' which are each provided with an inner stop 20, 20 ', each of which interacts with a stop 19 or 19' of the respective perforating needle holder element 2 or 2 ', as shown in particular in FIG . The stop sleeves 7, 7 ¹ are rigidly attached by gluing or knurling, as shown in FIG. Both capsule holder parts 3 »4 each have a passage 18, 18 ', which ^{allow the passage of the perforating needles 5, 5 1} and air. In order to keep the perforating needle 5, 5 'separated from the capsule 16, two return springs 21, 21' are arranged pressed together at the jacket-shaped ends of each perforating needle holder element 2, 2 ¹ in an annular cavity for receiving cylindrical return springs 21 and 21 ', respectively that the return springs 21 and 21 'work between the bottom of the return spring holding cavity and the ends of the extension of the perforating needle holder element 2 and 2 ¹ , respectively. 14 is an

The invention · is based on the object of a Inhaler improved over the stated state of the art of simple execution, quick and safe operation and reduced dimensions.

The invention relates to an inhaler for contained in a capsule to be pierced by means of a perforating needle pi / lvüröraige substances, which with the help of a Pump are to be distributed, with an upper part on its EndQ the powdery substance emerges, a middle one Part and a lower part for connecting to the pump. The above-mentioned problem is thereby solved solved that the inhaler through a stationary middle element as the middle part, which of two, preferred x <travels is formed by screwing or a bayonet coupling to be connected to each other capsule holder parts and has a cavity for receiving the capsule, and two perforating needle holder elements which are movable relative to one another in the upper part and lower part, which in the two. Capsule holder parts against the action of return springs are telescopically movable in, is characterized.

According to one embodiment of the inventive concept, it is expedient that the two capsule holder parts of the middle Element with stop sleeves plus one inner stop each, each of which in the rest position with a stop of the respective perforating needle holder element in Is to bring plant, are connected, preferably by gluing or friction locking, and in the Working position or the stop of the respective perforating pin holder element when the capsule is pierced is to be brought into contact with the respective capsule holder part.

Eej is also advantageous according to a further embodiment, that the Roibun ^ sVerriogelung the Perforiorcad 1-halterelcsento with dera upper Clement respectively the iliiaehluio piece of the lower üloLientoo for the Pu.ipc üox-jio the coupling lock of the stop muffon. with the caps 1 holder parts formed by Hilcporippen with Öägezhnen

Pre-travel is the lower element of the inhaler from such a porin that at ITichtp.etorauch the inhalator body is within the pump turned upside down »more expediently w iao with aurgere Position of the Purape towards Unton, can be inserted, thereby making a considerable verrincei-us des PlatKbodarfcs in addition to an increase in usability and a pleasing quality compact appearance of the device can be achieved.

According to a particularly advantageous embodiment of the Er finding is therefore the profile of the cylindrical surface dos lower part of the inhaler smooth or polished and uniform and of a protrusion on which the mouth part of the pump is brought into the system by frictional locking, interrupted. Touch is preferred make the cylindrical surface of the lower part of the inhaler ^ locking points with the straight surface of the projection for frictional locking with the pump when the inhaler is ready for use. Also are preferred the contact points of the cylindrical surface of the lower part of the inhaler with the curved surface of the protrusion of the locking position for friction locking with the pump while the inhaler is at rest.

The inhaler of the present invention is illustrated by the following Embodiment explained in more detail in connection with the accompanying drawings.

FIG. 4 shows the inhaler in front of FIG. 1 after it has been used or after piercing a capsule contained therein »

According to FIGS. 1 and 4, the inhaler comprises an upper element 1, from which a powder distributed by a capsule 16 after being pierced is made to flow out, and a connector or mouthpiece 10 for connecting the inhaler to a conventional pump 15 Pump 15 can have a large number of designs, it is not described in detail and is only shown schematically. Perforiernadelh ^ lterelemente or -anschlussstüclie 2, 2 'are attached in the upper element 1 or in the connection piece 10, the connection being brought about by gluing or by means of bundles 13t whose profiles according to FIG Perforating needle 5 or 5 ^{1 is} pushed into dos Porforiornadelhultcrolcment 2 or 2 'and is held by four radial ribs 9 or 9 ¹ ' which, in addition to holding the perforating needle 5 or 5 *, allow air to pass through.

AO

The ribs 9 »9 ¹ both define air passages and connect the perforating needle holder to the body of the relevant perforating needle holder element 2 or 2 '.

In Figure 1, the internal stops 20, 20 'of the stop sleeves 7 »7 ¹ into abutment with the stops 19' 19 'of the Perforiernadelhalterelemente 2 shown 2 ^1, while in Figure 2, the stops 19 * 19' of the Perforiernadelhalterelemente 2, 2 ^{1 are in} contact with the tubular extensions 6, 6 ^{1 of} the capsule holder elements J, 4.

In Figures 1 and 4, the profile is the cylindrical Surface of the lower part 10 of the inhaler body, which by frictional locking with the pump 15 of suitable Dimensions is connected, smooth or polished and uniform and by a projection 11, the points of contact 12, 12 'with the cylindrical surface of the lower Part 10 of the inhaler body represent the stop points for frictional locking with the pump 15 when the inhaler is ready for use or is not used, interrupted.

The way the inhaler works is as follows:

First, the inside of the pump 1.5 is reversed, expediently with the pump 15 in an upright position below, located inhaler body removed from the latter and within the same by friction locking in its with the Pompe 15 arrangement in the same direction, expediently in the upright position with the upright position of the pump 15, connected to the pump 15 Then the capsule holder part 4

unscrewed from the capsule holder part 3 and inserted the capsule 16, whereupon the upper element 1 and the connecting piece 10 of the lower part are moved towards one another, that is to say one Shortening or compression of the inhaler along the arrows A and B is brought about, resulting in two diametricals opposite punctures in the capsule 16 leads. It is therefore sufficient to press the pump 15 to dispense the powdery content the capsule 16 in a cavity of humans or animals, such as nasal cavities or other cavities of the human or animal body.

From the above goes the great simplification, which was achieved by the inhaler according to the invention with very few parts, which is why the assembly only with very low cost.
